Oil palm frond is known to be the largest contributor to the oil palm residues, providing
up to 50.3% of the total residues. Since it has a very limited utility, an initiative was taken
by this study to investigate its suitability for bio-oil production. Hence, slow pyrolysis was
conducted in an experimental setup equipped with a fixed bed reactor and a liquid collection
system. From the experiments, the effect of reaction temperature on the bio-oil yield was
examined. The characteristics of the obtained bio-oil were also investigated to study its
potential as a substitute of phenol. It was found that at reaction temperature of 375oC,
highest yield of bio-oil was obtained at 38.4 wt%. Meanwhile, the characteristics of oil palm
frond and its bio-oil were found to be approximately similar to the characteristics of typical
softwoods and their bio-oil. Most softwood biomass has been successfully used as a phenol
substitute. Therefore, the potential of this bio-oil to be used as a phenol substitute was
enhanced.
